audit

To verify hexagonal architecture conformance in a .NET solution, run an audit against the codebase to validate layer boundaries, repository ports, and MediatR abstractions. This generates a comprehensive report identifying missing ports and boundary violations across Functions, Application, Domain, Shared, and Adapters layers.

An architecture audit for CQRS and MediatR projects checks for correct handler interfaces, domain events, and Shared abstractions. It ensures Result-based return types are used correctly and validates that no business logic leaks into adapters or infrastructure, maintaining strict layer dependency compliance.

You need specific patterns to use this audit tool effectively. It is applied to .NET solutions implementing hexagonal architecture with CQRS and MediatR patterns, requiring distinct Functions, Application, Domain, Shared, and Adapters layers to accurately validate dependencies and conformance.

To identify architecture drift and missing ports in domain-driven design, execute an architecture health check across your codebase. This detects potential violations and confirms the presence of required repository ports and MediatR abstractions, ensuring layer boundaries remain strictly enforced.

The best way to prevent business logic from leaking into infrastructure adapters is to perform automated layer dependency validation. This verifies that adapters reference only allowed layers and confirms that Result-based return types and domain events are correctly implemented within the application core.
